IMPROVEMENT IN- PowD'ER-EJEcToRs.

Specitication forming part of 'Letters Patent No. 176,279, dated April18, 1876; application filed February 24, 1876.

To all whom it may concern:

Be itknown that I, CHARLES GnINNoox, of Brooklyn, in the county ot Kingsand State of New York, have invented certain new and useful Improvementsin Powder-Ejector, of which the following is a specification:

This invention relates to an improved injector or powderfgun, forthrowing obnoxious or poisonous powders into or upon places oecupied byinsects, for destruction and extermination of the same; its object beingto provide an apparatus that can be cheaply constructed, and that can beconveniently lled and handled, and in which the contents 'are in fullview of the operator, in order to indicate when it is necessary toreplenish the ap paratus.

The invention consists ot' a ask or other suitably shaped receptacle,constructed of glass or other suitable material, and provided withanopen mouth and bottom, the mouth being adapted to receive a cap orstopper,

provided with a discharge-tube, having' a ilexible-jointed extensionprojecting into the interior of the receptacle, and the open bottombeing provided with a flexible bottom, distended from the inside bymeans of a spiral or other spring. The inner ilexible end of thedischarge-tube is adapted to fall to the lower side of the receptacle inwhatever position the flask may be held, in order to provide for thedischarge of the last portions of the contents of the ask, and is madein sections, jointed together, in order to enable it to be shortened orlengthened as the bottle is tilled and emptied, so that it may beproperly inserted and will always fall in proper position. The exiblebottom may be made removable, in order to allow the flask to be Iilledfrom the bottom 5.

or it may be permanently attached to the flask, the ask being formedwith an external groove around its lower edge, in which the bottom maybe secured by means of al1 elastic band of rubber, metal, or othermaterial, or by a binding cord or wire Otl any suitable-material.

In the drawing, Figure 1 represents a per- .spective View of myapparatus, and. Fig. 2 a

sectional view ot' the same. v

The letter A represents a flask or other shaped receptacle for thepowder,constructed open mouth and bottom. B represents a stopper or cap,adapted to it into or be otherwise secured to the mouth of the flask. Crepresents a disehargetube, extending through the stopper or cap, andprovided at its inner end with a iiexible tube or extension, D, formedin sections, which are jointed together in such manner that the sectionsmay be separated and thetube shortened, as desired.

The object of such construction of the ilexible extension is to enablethe same to be shortened, as desired, when the flask is filled throughthe mouth, so as to enable the cap and tube to be inserted when thebottle is completely filled, and to be extended as the flask becomesempty.

Around the exterior of the edge of the open mouth of the flask is formeda groove or annular recess, E, for the purpose ot' receiving and holdingthe edge ofthe liexible bottom F. Said bottom is composed of exible cupor disk, ot rubber, oiled silk, or other suitable material, secured orbound into the groove or recess E by means of an elastic or detachableband of rubber, metal, or other suitable material, or by a permanentbinding cord or wire of any suitable material.

G represents a spiral spring sitting within the flask, its upper endhaving a bearing against the interior of the shoulder of the ilask, andits lower end against a rigid disk, H, of metal or other material,sitting against the flexible bottom F.

The object of said spring is to keep the tlexible bottom distendedoutwardly, and allow it to be pressed inwardly to discharge the powder.

As thus constructed, it will be seen that the powder can always bedischarged as long as any remains in the ilask, as the end of theflexible extension of the discharge-tube always lies at the lowest partof the ilask in whatever position it may be turned.

'By constructing the flexible connection in sections, provision is madefor the insertion of the top and tlexible extension in the ask, andproviding for the thorough discharge of the powder whether the flask isfull or partially full, and by means of the iexible bottom a convenientmeans of discharging the powder is obtained.

vided with a exible sectional discharge-tube, D, the whole beingconstructed and arranged substantiali y as described, for the objectspecified. Y

In testimony that I claim the foregoing I have hereunto set my handinthe presence of the subscribing witnesses.
